LabChem® Phosphate Standard, 500ppm (1mL = 0.5mg Po4), 500mL

LabChem® PHOSPHATE STANDARD, 500ppm (1mL = 0.5mg PO4) is a certified phosphate calibration standard prepared to a concentration of 500 parts per million. It is manufactured under controlled conditions to provide a precisely known, traceable concentration for instrument calibration. This level of accuracy is essential for reliable quantitative analysis of phosphate across a range of sample types.

It is commonly used to calibrate colorimetric and ion chromatography methods for phosphate determination in water and wastewater testing, as well as to verify instrument accuracy over time. Its certified concentration helps support consistent, reproducible calibration curves. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
